Graph \Graph\ (gr[.a]f), n. [See {-graph}.] (Math.)
1. A curve or surface, the locus of a point whose
co["o]rdinates are the variables in the equation of the
locus; as, a graph of the exponential function.
[Webster 1913 Suppl.]

2. A diagram symbolizing a system of interrelations of
variable quantities using points represented by spots, or
by lines to represent the relations of continuous
variables. More than one set of interrelations may be
presented on one graph, in which case the spots or lines
are typically distinguishable from each other, as by
color, shape, thickness, continuity, etc. A diagram in
which relationships between variables are represented by
other visual means is sometimes called a graph, as in a
{bar graph}, but may also be called a {chart}.
